As a fire chief, you know that regular maintenance extends the lifespan of your fire trucks. That’s why you do it. But have you ever wondered why these proactive measures improve the longevity of your fleet? Sure you have, which is why we’re going to give you five reasons right here.

#1: Preservation Of Structural Integrity

The structure of your fire trucks—including the chassis, frame, and body—is considered the truck’s foundation and provides support for the entire vehicle. If the body, frame, or chassis begins to deteriorate, the lifespan of the whole fire truck could be compromised. By performing regular maintenance and inspections, you give your crew the opportunity to identify and address any structural weaknesses or damage before these issues cause damage to the rest of the vehicle or result in a catastrophic failure.

#2: Proactive Component Replacement

Fire trucks are equipped with numerous components that undergo wear and tear in the course of every call, and even when they are sitting idle in the station. These components—such as belts, hoses, and filters—have finite lifespans and need to be proactively replaced before they reach the end of their usefulness, or they could fail unexpectedly and impact the rest of the vehicle. For example, a failed belt may damage pulleys or other engine components. By replacing parts before they reach the end of their service life, the risk of breakdowns and associated damage to other components is reduced and the lifespan of the vehicle is extended.

#3: Prevention Of Corrosion

Firetrucks are exposed to elements that can lead to corrosion, especially in regions with salted roads or high humidity. Corrosion often leads to the formation of rust on metal surfaces, which can compromise the functionality of various components like brake lines, fuel lines, and suspension parts. Regular inspections and corrosion prevention measures such as applying rust-resistant coatings to the interior, engine, and exterior help prevent rust-related failures and ensure that these critical components operate effectively for as long as possible.

#4: Preservation Of Fluids

Engine oil is essential for lubricating the internal components of the engine, reducing friction and preventing wear. Regular checks and timely oil changes help maintain proper lubrication and prevent premature wear on engine parts.

Coolant plays a critical role in regulating engine temperature. Maintaining recommended coolant levels and using the right coolant help prevent overheating and protect the engine from extreme temperatures.

Brake fluid is essential for transmitting hydraulic pressure within the brake system and allowing for effective braking. Regular checks and replacements of brake fluid help maintain the integrity of the brake system, preventing issues such as brake fade and ensuring reliable stopping power.

Transmission fluid is responsible for lubricating and cooling the transmission components. Checking and changing transmission fluid regularly contributes to smoother gear shifting, prevents excessive wear on transmission parts, and enhances overall transmission functionality.

Power steering fluid is essential for smooth and responsive steering. Regular maintenance of power steering fluid helps to optimize operation of the power steering system, preventing issues such as component damage and stiff steering.

Regularly checking and changing essential fire truck fluids like oil; coolant; and brake, transmission, and power steering fluids prevents the contamination and breakdown of these fluids. This protects the fire truck’s engine and, in turn, contributes to the extended lifespan of the fire truck.

#5: Mitigation Of Environmental Damage

Firetrucks often operate in challenging environments, including exposure to smoke, chemicals, and debris. Regular cleaning and maintenance help mitigate the environmental damage these factors can cause, preserving the vehicle’s components.

In debris-filled environments like areas affected by fires, accidents, or natural disasters, debris can accumulate in critical areas—such as radiators and air intakes—and lead to overheating and reduced efficiency. Regular cleaning helps prevent debris buildup and improves ventilation and cooling.

Rubber components—such as tires, hoses, and seals—are susceptible to environmental degradation. UV exposure and exposure to chemicals can lead to dry rot and deterioration. Regular cleaning and the use of protective coatings or conditioners can help mitigate environmental damage and preserve the flexibility and functionality of rubber components in the long run.

Environmental factors can also impact your fire truck’s electrical systems and lead to malfunctions and failures. Moisture, dust, and contaminants can compromise electrical connections and components. Mitigating environmental damage through protective measures, such as weatherproofing and regular inspections, helps preserve the functionality and lifespan of the firetruck’s electrical systems.

Adhere To Manufacturer Recommendations

No one knows your fire truck like the manufacturer. We build them inside and out, after all. That’s why we encourage you to read and follow the instructions in your fire truck manual. Following your fire truck manufacturer’s instructions and recommended maintenance schedule will help ensure your fire truck is operating within its intended parameters and contribute to a longer lifespan.
